We had a lovely time staying at Pupe's beautiful shop house. The house is excellently decorated, clean and well maintained. The location of the house is very good, with good connections to the rest of Bangkok, and sits above the owner's tapas bar. Pupe made for a great host, and was there for every question we had.
One thing to be aware of, if you are staying as a group, is that the house does not afford much privacy: the two rooms are joined together and the shower is visible to other guests. However, this is easy to work around and would not be a problem for a couple.
